Desired islanding detection method not only can detect islanding within acceptable duration, but also require it has less adverse impact on power quality. This paper presents an active islanding detection method for a distributed resource (DG) unit which is coupled to a utility grid through grid-connected converter. With the proposed method which is based on adding periodical disturbing current through...
If distributed generation is to become a significant source of energy in the future, it will have to work in conjunction with the transformers supplying the distribution network to provide adequate voltage quality for customers. Current practice is to prohibit distributed generation from actively participating in voltage control. However, this approach does not take full advantage of the capabilities...
The use of distributed generation (DG) in distribution system is expected to increase in the near future due to its positive impacts such as voltage support, improved reliability, small size and losses reduction. However DGs may have negative impacts on power quality, such as voltage regulation, harmonic distortion, islanding and confliction with relaying and reclosing. This study investigates the...
